Bakuchiol is a plant‑derived antioxidant most commonly sourced from the babchi plant (Psoralea corylifolia). It’s frequently discussed alongside retinol because it can help improve the visible signs of aging—such as uneven tone and fine lines—without being a vitamin‑A derivative.

Mechanistically, bakuchiol is valued for its antioxidant and soothing profile and for its ability to support a smoother, more even‑looking complexion over time. Many formulas position it as a “retinol alternative” for people who want a gentler pathway to visible refinement, especially when dryness or sensitivity is a concern. Because it isn’t retinoic‑acid–based, it’s often chosen for routines where users want retinoid-adjacent benefits while keeping the overall irritation load low.

Bakuchiol also shows up in hybrid formulas with retinoids; in these, it’s often used to enhance overall results and improve comfort. As with any active, outcomes depend on the full formula and consistent use—pair with daily sunscreen for best long‑term tone and aging support. Look for concentrations and supporting ingredients (like barrier-repair lipids) that match your skin type.
